Application filed February 15, 1913. Serial No. 748,643. 7

To all gohom it may concern:

Be it known that we, HENRY A. CARPENTER, ROBERT L. HIBBARD, and ARTHURW. WAR- NER, citizens of the United States,residing at Sewickley, in thecounty of Allegheny and State of Pennsylvania, have invented certain newand useful Improvements in Apparatus for Charging and Discharging Gas-Retorts, of which the following is a specification.

Our invention relates to improvements in apparatus for charging anddischarging gas retorts, and particularly to apparatus of the charactershown and described in a pending application Serial Number 530,883 filedNovember 29, 1909.

Among the objects of the present invention are: to provide means forshaping or leveling the coal contained in the charger and discharger toprevent the contents of the charger and discharger from striking theupper edge of the mouth of a retort and be ing thrown into the retorthouse; positively operable means for actuating the shaper; means forsupporting the charger and discharger located at the forward end of theapparatus; means for adjusting the shaper to desired positionsrelatively to the charge of coal being introduced to a retort; bufiingmeans located at the forward end of the apparatus adapted to makecontact with a horizontally movable carriage on which the combinedcharger and discharger is carried; and a new and improved combinedcharger and discharger.

In the accompanying drawings which illustrate an application of ourinvention: Figure 1 is a part side elevational view and a part sectionalview of the forward end of the charging and discharging apparatus; Fig.2 is a part elevational view and a part sectional view of the same, thesection being taken on line 11-11 of Fig. 3; Fig. 3 is a part frontelevational view and a part sectional view of the forward end of theapparatus; Fig. 4 is a sectional view of the forward end of the chargerand discharger members, the section being taken on line IV IV of Fig. 5looking in the direction of the arrows; and Fig. 5 is a front view ofthe forward end of one of the chargers and dischargers.

As illustrated and as preferred, the combined charger and discharger 2are mounted on a horizontally movable carriage 3, said carriage beingsupported on ways 4 by means of rollers or wheels 5 and 6, the wheels 5being mounted on the upper faces of the ways a, and the wheels 6 beingde signed to make contact with the underside of said ways L.

The carriage, together with the charger and discharger, are adapted tobe moved forward and backward by means of a rotative screw member 7projecting through a nut 8 depending from the carriage. The horizontallymovable carriage and the mechanism for moving it form no part of thepresent invention, said carriage and mechanism being described and shownin the pending application aforesaid, and it is deemed unnecessary tofurther describe the same in this specification.

The means for shaping the charge of coal contained in the charger anddischarger, as illustrated, include a roller member 9mounted on a shaft10, which shaft has its bearings in members 11 supported by and movablewith a movable frame 12. Frame 12 is mounted on a shaft 13, the latterhaving its ends supported by brackets 14: projected outwardly from aplate secured to a trans versely extending girder 15, the latter beingcarried on the charging and discharging apparatus.

The frame 12 carrying the roller 9 may be moved toward or away from thecombined charger and discharger, and for this purpose we provide anadjusting screw 16 extended through a member 17 as particularly shown byFig. 2. The roller shaper or leveler 9 is preferably of the form shown,and is designed to be rotated at substantially the same rate of speed asthe movable carriage is driven by the driving screw 7, and for thispurpose, we have provided positively operable means, said means beingconnected with the driving screw 7 and actuated thereby.

The positively operable means as shown include a gear wheel 20 mountedon the forward end of the driving screw 7, a gear 21 located below saidgear 20 and adapted to mesh therewith, a shaft 22 on which the gear 21is mounted, a bevel gear 23 secured to the opposite end of shaft 22, abevel wheel 24,

the latter being mounted on one end of a laterally extending shaft 25,which latter shaft has secured on its opposite end, a bevel gear 26. Inaddition to the parts mentioned, this driving mechanism includes avertically disposed driving rod 27 having at its lower end a gear 28adapted to mesh with the gear 26; horizontally disposed shaft 13 has abevel gear 30 mounted on an end thereof, said gear 30 being designed tomesh with a gear 31 carried on the upper end of the vertically extendingshaft 27. On the opposite end of shaft 13, we provide a gear wheel 32which wheel meshes with a large wheel 33 mounted on an end of the rollershaft 10.

A mouth of a horizontally disposed retort is indicated by the numeral 31, and the position of the charge contained in the charger anddischarger is indicated by the dotted line 35. The manner of depressingor leveling the charge preliminary to its introduction into the retortso as to prevent the upper surface of the charge from striking theretort opening is particularly shown by Fig. 3.

The means employed for supporting the charger and discharger includerollers 36 disposed preferably directly under the leveler 9 and onopposite sides of the charger and discharger, said rollers beingsupported from a plate member 37 located at the forward end of theapparatus. These rollers have their axes relatively inclined in suchmanner as to afford a support against sagging both in vertical andlateral directions.

Located on opposite sides of the apparatus and at the forward endthereof, we provide buifing or shock absorbing springs 38 designed tomake contact with the respective wheels 5 of the carriage as thecarriage reaches the limit of its forward movement.

Fig. 4 of the drawings particularly shows the forward ends of a pair ofscoops constituting the charger and discharger. As shown herein, and asmore particularly described in the pending application above mentioned,the charger and discharger comprises a pair of scoops or trough-shapedmembers, with each scoop or member including an outer member a and aninner member 6. In the new form of charger and discharger as shown byFig. 4:, the outer members a are each provided with a pro jecting member0, said member 0 having a head d formed with a curved slit e. Each ofthe inner members Z) are also provided with a projecting end portion f,and the outer ends of the portions f are respectively designed to beentered in the respective slits of the heads (Z. This particulararrangement of the forward ends of the scoops is of particular advantagein connection with rollers 36. As will be seen the heads cl act somewhatas guides for the members 6 (through their continuations f), so thatwhen the scoops are projected and given their turning movements, theweight of the projected portions of the scoops together with the weightof the coal carried thereby will not be effective to cause adisarrangement of the scoop members at such end, each scoop memberretaining its'individuality in this respect, and the rollers 36, duringthe movement of the scoops into their forward positions, preventinglateral sagging of the scoops relative to each other, thus tending toprevent the charge from being dropped between the scoops while passingto charging position.
